Abstract
The present status of the Lambda(1405) structure study in chiral dynamics is briefly reviewed. It turns out that the Lambda(1405) resonance can be described by hadronic dynamics. The idea of the hadronic molecular state is extended to kaonic few-body states. It is concluded that, due to the fact that K and N have similar coupling nature in s-wave Kbar couplings, there are few-body quasibound states with kaons systematically just below the break-up thresholds, like KbarNN, KbarKN and KbarKK, as well as Lambda(1405) as a KbarN quasibound state and f_0(980) and a_0(980) as KbarK.
